Abstract
Twin roll caster for casting metal strip comprises casting rolls (11) between which is formed a casting pool (16) of molten metal. The casting pool is confined at each end of the roll nip by end closure plate (22). Alternating electric current is supplied to electrical conductors (33) disposed outside the closure plate (22) so as to generate an electromagnetic field which extends through the closure plate and pushes back molten metal at the conjunctions (27) between the closure plate (22) and the rolls (11).
